BEST MODE FOR CARRYING OUT THE INVENTION An on-vehicle electronic device equipped with a movable display panel (display monitor) according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1A is a plan view for explaining the structure (internal structure) of the on-vehicle electronic device. Also, FIG.
(B) is a side view of the display panel 1. Note that FIG.
FIG. 6 is a diagram showing a state in which the display panel 1 is not tilted up. Then, when the display panel 1 is manually tilted up as described later, the front surface (display surface) faces the front surface, as in the conventional vehicle-mounted electronic device shown in FIG.

Returning to FIG. 1, this vehicle-mounted electronic device is roughly configured to include a display panel 1, a panel holding assembly 2, a mechanical assembly 3 and a main body 4, as shown in the drawing. .

The display panel 1 is, for example, a panel (monitor) having an LCD (Liquid Crystal Display) unit or the like arranged on the front surface (bottom surface in FIG. 1), and the main body 4
It is controlled by a control circuit or the like (not shown) inside to display predetermined characters and graphic information. Further, on the back surface of the display panel 1, as shown in FIG.
1 is fixedly arranged.

When the display panel 1 is tilted up, the upper and lower slide rack gears 11 mesh with transmission gears (transmission gears 36a and 36b of the panel holding assembly 2) described later, respectively, and the display panel 1 is rotated as the transmission gears rotate. Slide with it. In addition, as shown in FIG. 1B, the vertical slide rack gear 11 has guide grooves 12 on its side surface.
Is engraved. A guide roller (a guide roller 22 of the panel holding assembly 2) described later is fitted in the guide groove 12, and the display panel 1 is held by the panel holding assembly 2 in a slidable manner. Further, on the back surface of the display panel 1, a notch portion (not shown) for engaging with a panel lock member (panel lock member 21 of the panel holding assembly 2) described later is formed.

The panel holding assembly 2 is shown in FIG.
As shown in FIG. 2, the upper plate 2a, the two side plates 2b, and the inclined plate 2c inclined at a predetermined angle with respect to the upper plate 2a hold the display panel 1 movably, and the mechanical assembly 3 Is rotatably supported by. Specifically, the panel holding assembly 2 includes a panel lock member 21 in a hole 2d formed in the upper plate 2a and the inclined plate 2c.
Is rotatably held. Two (four in total) guide rollers 22 are axially supported inside each side plate 2b. Further, a hinge 23 is provided at the end of the slope plate 2c.

As shown in FIG. 2B, the panel lock member 21 has a substantially rectangular parallelepiped shape with a claw portion 21a and a projection portion 21.
b, a shaft hole 21c, and a pin 21d. The panel lock member 21 is rotatable by the panel holding assembly 2 by fitting a predetermined support shaft provided in the hole 2d of the panel holding assembly 2 into the shaft hole 21c with the spring 21e interposed therebetween. Held in. At that time, since the spring 21e is hooked on the pin 21d and fixed, the restoring force of the spring 21e urges the panel lock member 21 toward the tip of the claw portion 21a. And the panel lock member 21 is
The claw portion 21a engages with the notch formed on the back surface of the display panel 1 by rotating about the shaft hole 21c. When the protrusion 21b is pressed, the protrusion 21b rotates in the opposite direction around the shaft hole 21c, and the engagement between the cutout portion and the claw portion 21a is released.

The guide roller 22 is rotatably supported inside the side plate 2b and fits into the guide groove 12 of the vertical slide rack gear 11 as shown in FIG. 1 (b). The panel holding assembly 2 is provided with the guide groove 12
The display panel 1 is slidably held along the line. It is assumed that the display panel 1 cannot slide when the claw portion 21a of the panel lock member 21 is engaged with the cutout portion formed on the back surface of the display panel 1.
The display panel 1 is slidable when the protrusion 21b is pressed and the notch and the claw 21a are disengaged.

The hinge 23 is joined to the end of the mechanical assembly 3. Then, via this hinge 23,
The panel holding assembly 2 is rotatably held by the mechanical assembly 3.

Returning to FIG. 1, the mechanical assembly 3 slides the display panel 1 horizontally with respect to the main body 4,
Further, it is a drive mechanism for sliding the tilted-up display panel 1 in the vertical direction (vertical direction with respect to the main body 4) on the front surface of the main body 4. Specifically, the mechanical assembly 3 includes two side arms 31, a horizontal slide motor 32, and a coaxial gear 33 on a predetermined mechanical chassis.
a, 33b, connecting shaft 34, and vertical slide motor 35
And transmission gears 36a and 36b are arranged. Since the end portion of the mechanical assembly 3 is connected to the panel holding assembly 2 by the above-mentioned hinge 23, the mechanical assembly 3 is not attached to the panel holding assembly 2.
The display panel 1 is rotatably held via.

The two side arms 31 are coaxial gears 33.
A and 33b and transmission gears 36a and 36b are pivotally supported.
The horizontal slide motor 32 is arranged in the vicinity of the coaxial gear 33a, and meshes with the coaxial gear 33a via, for example, a helical gear fitted to the rotating shaft. Then, the horizontal slide motor 32 applies the driving force generated by the rotational drive to the coaxial gear 3
3a, etc.

The coaxial gears 33a and 33b are pivotally supported by a connecting shaft 34. The connecting shaft 34 is sandwiched between the two side arms 31. Coaxial gear 33a
Engages with a helical gear or the like of the horizontal slide motor 32 described above. The coaxial gears 33a and 33b mesh with a slide rack gear (two slide rack gears 41 of the main body 4) described later. When the horizontal slide motor 32 is rotationally driven, the driving force is transmitted to the coaxial gear 33a, and the coaxial gears 33a and 33b are both rotated by the connecting shaft 34. Then, due to the rotation of the coaxial gears 33a and 33b, the mechanical assembly 3 horizontally slides on the meshing rack gear for sliding. At this time, the display panel 1 is also slid horizontally in the same manner as the panel holding assembly 2 connected to the mechanical assembly 3 by the hinge 23. That is, according to the rotation direction of the horizontal slide motor 32, the display panel 1 moves in the discharge direction (L in the drawing).
Direction) or the storage direction (R direction in the drawing).

The vertical slide motor 35 includes a transmission gear 36.
It is arranged in the vicinity of a and is meshed with the transmission gear 36a via, for example, a helical gear fitted to the rotary shaft. Then, the vertical slide motor 35 transmits the driving force generated by the rotational drive to the transmission gear 36a.

The transmission gears 36a and 36b are pivotally supported by the above-mentioned side arm 31. Also, the transmission gear 36a
Engages with a helical gear or the like of the vertical slide motor 35 described above. Further, the transmission gear 36a (transmission gear 36b)
As shown in FIG. 3, when the display panel 1 is tilted up, it engages with the above-described vertical slide rack gear 11. Then, as the transmission gear 36a rotates in accordance with the rotational drive of the vertical slide motor 35, the display panel 1 slides in the vertical direction together with the meshing vertical slide rack gear 11.

Returning to FIG. 1, although not shown, the main body 4 includes a storage portion for storing the display panel 1 and the like, and the display panel 1.
A control circuit or the like for controlling the display of (LCD unit or the like) is arranged. Similarly, a drive circuit and the like for driving the horizontal slide motor 32 and the vertical slide motor 35 are also arranged. Further, two slide rack gears 41 are fixedly arranged on the main body 4.

The rack gear 41 for sliding is the coaxial gear 3
It meshes with 3a and 33b. That is, the main body 4 slidably holds the mechanical assembly 3 via the sliding rack gear 41 and the like.

The specific operation of the vehicle-mounted electronic device according to this embodiment will be described below with reference to FIG. 4A to 4E are schematic diagrams for explaining the operation of the display panel 1 stored in the main body 4 until the display panel 1 is placed in the use position on the front surface of the main body 4. The on-vehicle electronic device is assumed to be attached to a storage location in the vehicle (for example, an opening of the instrument panel).

First, with the display panel 1 housed inside the main body 4, the horizontal slide motor 32 is rotationally driven, and the mechanical assembly 3 slides. That is, the rotational driving force of the horizontal slide motor 32 is the same as that of the coaxial gear 3.
3a, the coaxial gears 33a and 33b rotate together. Then, the mechanical assembly 3 slides on the sliding rack gear 41 by the rotation of the coaxial gears 33a and 33b. With the movement of the mechanical assembly 3, as shown in FIG. 4A, the display panel 1 slides toward the front surface (in the arrow direction) of the main body 4.

When the display panel 1 (mechanical assembly 3) moves to a predetermined position, the horizontal slide motor 32 stops rotating. That is, as shown in FIG. 4B, when the display panel 1 reaches a predetermined position at which the display panel 1 is completely discharged to the front surface of the main body 4, for example, a micro switch is pressed to rotate the horizontal slide motor 32. Stops.

In this state, the user manually tilts up the display panel 1. That is, since the panel holding assembly 2 is rotatably held by the hinge 23 with the mechanical assembly 3, the display panel 1 pressed by the user is held by the panel holding assembly 2 as shown in FIG. 4C.
Rotate with. At this time, even when the display panel 1 is rotated and tilted, the claw portion 21a of the panel lock member 21 is engaged with the cutout portion formed on the back surface of the display panel 1 (projection portion). The display panel 1 does not slide when 21b is not pressed.

The display panel 1 continues the tilting operation while being pressed by the user, and rotates to a position orthogonal to the main body 4, for example, as shown in FIG. When the display panel 1 is rotated to this position, the vertical slide rack gear 11
It meshes with the transmission gears 36a and 36b. At this time, the protrusion 21b of the panel lock member 21 is pressed by the end of the mechanical assembly 3. For this reason, the panel lock member 21 rotates, the claw portion 21a is disengaged from the cutout portion of the display panel 1, the panel holding assembly 2 becomes movable, and the tilting operation of the display panel 1 ends ( It will not be possible to rotate further).

When the tilt operation of the display panel 1 is completed,
For example, when the user presses the panel up / down button or the like, the vertical slide motor 35 is rotationally driven, and the display panel 1 remains orthogonal to the main body 4 as shown in FIG. Slide toward. That is, as the vertical slide motor 35 is driven, the transmission gear 36a rotates while meshing with the vertical slide rack gear 11, whereby the display panel 1 slides vertically.

By this vertical sliding movement, the display panel 1 is moved to a use position arbitrarily designated by the user (for example, a position where the air outlet of the air conditioner is not covered). As a result, the use position of the display panel can be adjusted appropriately.

In the above embodiment, since the display panel 1 is slid by the panel up / down button or the like, the user needs to operate the panel up / down button or the like every time.
However, since the user generally uses the display panel 1 at the same use position, the user may store the arbitrary use position once and automatically move to the use position from the next time. For example, when the tilting operation of the display panel 1 ends, the vertical slide motor 35 starts driving by pressing a micro switch or the like. Then, when the display panel is automatically moved to the stored use position, the vertical slide motor 35 automatically stops driving. In this case, the operation load on the user can be reduced.

The display panel 1 stopped at the use position
However, this may hinder the user from operating the buttons on the main body 4 and inserting / ejecting media. In such a case, the user, for example, presses the panel up / down button to raise the display panel 1 to the tilted up position (tilt up end position), and operates the buttons of the main body 4 and inserts / ejects media. To do. Then, the panel up / down button is pressed again to return the display panel 1 to the use position.
In order to omit such a button operation again, the display panel 1 moved to the tilt-up end position may be automatically returned to the use position. For example, when moving to the tilt-up end position, the timer is started by a predetermined timer, and when a predetermined time (arbitrarily settable) elapses, the up-down slide motor 35 starts driving to the stored use position,
The display panel 1 is automatically moved.

Further, when the medium is inserted, the display panel 1 may be automatically slid up and down without operating the panel elevating button. For example, a medium detection sensor or the like is installed on the display panel 1, and when the user brings the medium close to the insertion opening, the medium detection sensor detects the approach of the medium. Then, in response to this, the vertical slide motor 35 starts driving, and the display panel 1 is automatically raised to the tilt-up end position. In this case as well, the display panel 1 is automatically returned to the stored use position when a predetermined time elapses after moving to the tilt-up end position.

As described above, the above-described on-vehicle electronic device is
Since the display panel 1 is held by the panel holding assembly 2 (guide roller 22), rattling of the display panel 1 can be suppressed and mechanical strength can be improved. Further, since the drive system is integrated in one place, space saving can be realized and wiring can be easily routed. Further, since the tilt operation of the display panel 1 can be manually performed, mechanical strength is improved, space can be saved, and cost can be reduced as compared with the conventional vehicle-mounted electronic device. .

Further, the panel lock member 21 allows the display panel 1 to move only when vertically sliding, and the display panel 1 is fixed to the panel holding assembly 2 during other operations. Therefore, rattling of the display panel 1 can be suppressed during the tilting operation or the horizontal sliding operation. When the display panel 1 is rotated to the tilt-up end position (tilt up), the panel lock member 21 automatically disengages the display panel 1 from the panel holding assembly 2. On the other hand, when the display panel 1 is tilted down, the display panel 1 and the panel holding assembly 2 are automatically engaged. For this reason,
The user does not need to separately operate the engagement (lock) of the display panel 1 and the panel holding assembly 2.

Further, by storing the use position of the display panel 1, the user can automatically move the display panel 1 to the stored use position only by tilting up the display panel 1 manually. it can. In addition, after the display panel 1 is moved from the use position to the tilt-up end position and a predetermined time (which can be arbitrarily set) has elapsed, the display panel 1 is automatically returned to the use position. The operation load can be reduced.

As described above, according to the on-vehicle electronic device described above, the use position of the display panel can be appropriately adjusted.

In the above embodiment, the case where the drive system is all arranged in the mechanical assembly 3 has been described. However, a part of the drive system, for example, the transmission gears 36a and 36b, etc., together with the upper and lower slide rack gears 11 are displayed on the display panel. It may be arranged on the back surface of No. 1. In this case, the transmission gear 36
When the display panel 1 tilts up, the transmission gears 3a and 36b are constantly meshed with the upper and lower slide rack gears 11.
The driving force of the vertical slide motor 35 is transmitted to 6a and the like.

As described above, according to the present invention,
The use position of the display panel can be adjusted appropriately.
